Be it known that I, FRANK L. WANKE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Knockdown Stoves or Ranges; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to'` occupy very large individual space in the freight or express car and have to pay freightage or express accordingto their bulk rather than according to their weight. This is true of all stoves and especially true of cooking stoves or ranges, which are very bulky in their proportions and hence expensive in transportation, especially fo'r long distances, such as are found between the Eastern manufacturing cities of our country and the outlying Westl ern States and Territories. Indeed, so expensive has shipment been found that Eastern manufacturers have been unable to compete with manufacturers located in the W'est, and all because of the large space occupied by a single stove or range. jection I have sought to provide a range or stove which can be taken apart and packed so as to occupy practically no greater space than the parts themselves must occupy by reason of their own size and shape. This result is obtained by producing a stove in sepav rable parts, or what is properlyknown as a knock-down stove, adapted to be taken down and set up by any one who is skilled in stove manufacture and who has some familiarity with the construction of the stove as herein shown and described.

The invention, therefore, consists in a knock-down stove or range substantially as shown in the accompanying drawings and pointed out particularly in the claims.

To overcome this ob- In the accompanying drawings, Figure 1 is a perspective Viewv of my improved. stove or range. Fig. 2 is a longitudinal sectional ele- 55 vation on a line corresponding to 22, Fig. 5. Fig. 3 is a cross-section of the stove ona line corresponding to 3 3, Fig. 4. Fig. 4 is ahori- -zontal section looking down on a line corresponding to 4 4, Fig. 3. Fig. 5- is a perspec- 6o tive view ofthe stove, looking in at an angle from the front and side and showing some of the' parts in position, and particularly those parts relating to the oven. Fig. 6 is a front elevation, in perspective, of the back plate of the stoveshown in posit-ion in Fig. 5. Fig. 7 is a front elevation of the rear oven-plate. Fig. 8

'is a perspective view of the bottom plate of the plate, as in Fig. 6, and showing, also, oneof the side plates. Fig. l0 is a rear view of the back plate which is shown in perspective in Fig. v6. Fig. 1l is a perspective view, looking from the outside, of what may be termed 8o the smoke-box, which belongs on the rear of the back plate seen in Fig. lO. Fig. 12 is a perspective view of a part of one corner of a stove, showing the manner of connecting the parts by the corner-posts. Fig. 13 is a perspective view of the warming-oven separated from the stove and having its cover or top plate raised to show its construction and adaptation for seating on the said frame. Fig. 14 is a perspective front elevation of the 9o door of the warming-oven.

Referringnow to Figs. `l, 2,3 and 4, we see the several parts in their assembled relations, while in Figs. 5, 9 and 13, only some of the parts are assembled, and the remaining gures are details of parts. Each and all of the parts are constructed with reference, primarily, to their place and use in the stove, and, secondarily,with reference to their convenience for shipment' in a compact form; roo lastly, they are constructed to effect such temporary connection and union, one with another, as to make a firm and serviceable stove when erected and atvthe same time to be convenient for separation and for packing. To these several ends I have found it altogether preferable to'make the stove of steel plate, so that when it is erected it produces what is known as a steel stove or range.

Assuming, now, that the construction has been knocked down and shipped and reached its destination where it is again to be set up, we begin to assemble and build the parts togetherl as they are seen partly assembled in Fig. 5. First of all, let us assume that We take the back plate A, which has its vertical edges 2 and 2 bent outwardly at right angles, and a flange 4 along its top edge with a recess at the middle thereof for the smoke box or iiue. are provided each with Vertical right angled flanges 5, respectively, at their front and rear, and the front plate C, which has right angled vertical anges (i at its edges and horizontal fiange 7 along its top. All of these several plates have an angle strip 8 on their inside a short distance from their bottom edge and riveted on said plates and on the same horizontal plane and adapted to receive the down wardly projecting ange or edge 9 on the stove bottoni proper, or bottom plate D of the stove. This flange 9 extends entirely around the edge of plate D, andengages over the angle strips 8. In assembling the parts, it is convenient to connect the side and the front and rear and bottom plates together before putting into position and of the internal parts except the division plate or wall E on the bottom D. This division plate is made T- shaped and engages beneath the angle strips 12 on the bottom plate D to form a division Wallin the fine or draft channel at the bottom of the stove as clearly seen in Fig. 5;

When the four several wall plates A,B and C, which form the shell of the stove are assembled, theirangled vertical edges or flanges stand at right angles to each other, or sub` stantially so, as clearly seen in Fig. 12. Then, in order to connect the meeting wall plates at their angles and make a firm and ornamental corner connection, I employ the preferably castmetalcornerpostsF. Thesepostsaresubstantially cylindrical in cross section, as here shown,but they may have other form in eXte rior outline if preferred, and may be of more or less ornamental appearance than as shown, and have each four faces in pairs at right angles to each other and extending lengthwise of the posts and correspondingr to the angle ofthe edges and faces of the said plates. fel-ring to Fig. 12, and assuming that we have there a corner of plates B and C, and it is immaterial which corner is taken for the purpose of this description, we find that the two inner meeting faces b and 0,1espectively, make a insh corner of said plates, and that their anges, 5 and 6, project outward from b and c, respectively, at right angles to 1J and c and also to each other. The corner post F therefore, is constructed to face against both sides of the angle between b and 5 on the out Then we have the side plates 13 which' Thus, re- 1 side of the plate B, and the same with respect to the angles between c and 6 in the plate C, and it has vertical faces to correspond to the outside ofv both said angles their full depth and to fill the same and is so constructed that when it has been slid down over the corner of the said plates thus formed, the said plates will be brought together at their corners at right angles to each other 'and will be immovably and firmly tied together for all the purposes of use, the same as if they were originally formed in a single piece or were rigidly and permanently bolted together. Each of the four corners is provided with the sante style of post as shown in Fig. 12, and the several four said side plates and the bottom plate are tied together with each other and with the said posts as described, and this maybe considered the first step in assembling the parts of the stove.

Now, having the box of the stove set up in this way, we may proceed to place other parts in position. Next in order, then say we take the bottom oven plate G, Fig. 8, which has a downwardly projecting flange 10 along its front and rear edge's, respectively, adapted to engage over an anglepiece 12 on the in-v side of the front plate and a corresponding angle piece 13 on the inside of the back plate. This plate G, however, is shown also as having at one end a downwardly extending portion 15,which in turn has a right angle flange 1U at its bottom adapted to engage under an angle piece 17 on the stove bottom D. The portion 15 of the plate G constitutes a wall between the fine under the oven plate and the ash pit, and the said portion is preferably shown as formed ont of' the saine plate as the bottom portion G. I might, of course, form 15 separately from G and connect them in some suitable way. This plate G has a series of grooves or depressions 18 stamped into it which run from front to rear thereof and are intended to accommodate expansion and contraction resulting from the ordinary actions of the stove under heat or cold. Said plate, furthermore, has grooves or channels 20 formed along its sides and adapted to set therein the two side plates I'I- and *I- respectively. These plates at their rear have right angled fianges 22 and 23 adapted to engage behind the vertical angle pieces 2t riveted to the back plateA of the stove. These angle pieces 24 are made deep enough in their angles to also accommodate the flanges 25 on the vertical edges of the warming plate K, which is set in nextto the rear plate Abehind said angle pieces 24 and has a flange 2G along its bottom engaging behind the angle piece 13, Fig. 6. This plate K is constructed to form a heat circulating chamber at the rear of the oven, as plainly seen in cross section, Fig. 4, and has a series of perforations 27 at its top and bottom respectively so as to promote a draft in the chamber behind it and to facilitate heating the oven at that part where otherwise the tendency would be to cool.

Over

lOO

the top of the oven thus formed we have a top plate L which has down flanges 30 along its edges engaging in corresponding vgrooves in the side plates H and I, which grooves are formed by bending the said side plates in such Ways as to form substantially U-shaped grooves of a size adapted to receive and lock the flanges 30 of the plate L. This top plate L likewise has a series of parallel depressionsv direct draft around the oven and following the direction of the arrows in Fig. 5. The smoke box M shown in Fig. 1l is adapted to be attached to the outside of the back plate A within the angle strips 36, Fig. lO, and has flanges '37 along its edges to engage in said angle strips. This box is inserted from above and of course is easily removedand replaced. Referring to Fig. 5 it will be senthat plates B and I-I, respectively, between which comes the fire-pot, are provided with angle pieces 40 and 4l, which extend inward toward cach other and form supports for the fire grate as seen in Fig. 2, vand the grate bars N are arranged on a line substantially with these angle strips.

Referring to Figs. 3 and 4, I show an air chamber in the oven door corresponding in purpose and function to a like chamber at the rear of the oven andformed of two plates, O and P, front and rear respectively, and connected along their side edges by the castings 44 to which they are riveted, and together with said castings form a front oven door. The front plate O has a ventilator 45 in its center.

Over all the parts as hereinbefore described, I place a cast metal top plate R of the stove, which is secured by short screws to the [langes along the top edges of the plates forming the box of the stove and thus the main structure of the stove is made complete.

Now, as a finishing part I have the warm` ing oven, set on the stove as described. This oven consists of end plates 48 having lianges 49 along their bottom through which they are secured to the top plate of the stove, and the back plate 50 having a flange 5l at its bottom for securing it to the top plate of the stove. These three several plates 48 and 50 have corner posts 52 for connecting them at their flanged or right angled corners after the manner of connecting the four sides of the stove proper, and the said several plates have angle bars 53 on their inside to receive the intermediate bottom 54, which is set upon said.

to engage in said angle plates 55 and thus the warming oven is completed.' It will benoticed that the side plates 48 have anrinwardly bent portion 60 attheir top and front engaging against the front edge of the plate 54 and forming a finish along this edge, and the doorn S Fig. 14 has ears 62 at its ends by which it is hinged at 63 in the side plates 48, Figs. 13 and 5, and is adapted to be raised and lowered within the warmingoven. The pipe ortlue T extends' through this Warming oven as seen in Fig. 3, and a suitable damper 66 contrls the direct draft opening 34.
